JOSEPH BLAIS, OF ST. CHARLES, QUEBEC, CANADA.

SPECIFICATION forming part of Letters Patent No. 412,453, dated October 8, 1889. Applicationiled March 15, 1887. VSerial No. 231,011. I (No model.)

To @ZZ whom it may concern,.-

Be it known that I, JOSEPH BLAIS, of St. Charles, in the countyof- Bellachasa, in y the Province of Quebec, and in the Dominion of Canada, have invented a new and Improved Carriage-Axle,V of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved carriage-axle which permits of lubricating the axle-spindle without removing the carriage-wheel.

The invention consists in the construction and arrangement of parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in .the claims.

lReference is to be had to the accompanying i drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts of allthe figures.

Figure 1 is a side elevation of my improvenient. Fig. 2 is a longitudinal central section of the same. Fig. 3 is an end view of the inner end ofthe axle-bearing. Fig. 4 is a face view of a collar for holding the bearing on the axlef Fig. 5 is an end view of the outer end of the axle-bearing. Fig. 6 is a face view of the collar fogholding the bearing on the axle, and Fig. 7 is a face view of a collar held on the outer .end of the bearing.

The carriage-axle A is provided with a spindle B, having on its inner endl a fixed collar C, against which abuts the recessed end of the axle-bearing D, secured in any suitable manner to the hub of the carriage-wheel. Near the outer end of the spindleBis formed an annular groove E, in which project the ends of the set-screws F, screwing in the bear- 'ing D. The screws serve auxiliary retaining devices for the bearing D. The outer closed end of the 'latter is provided with the segmental projections D', (see Fig. 5,) which t into corresponding grooves formed on the inside of the collar G, (see Fig. 7,) provided with recesses G for the passage of the proj ections D.

The collar G is fastened by set-screws G2110 the hub of the wheel, and another set-screw G3 fastens the collar G to the bearing D.4 Be` tween the outer closed end of the bearing D and the outer end of the spindle B is placed a coiled spring H, and in the middle of the closed end ot' the bearing D is a lubricatinghole. Behind the collar C is formed on the axle A an annular offset I, on which tits loosely the collar J, abutting against the collar C, and provided with segmental projections J adapted to engage a corresponding groove formed on the inside of the annular flange D2, extending from the inner end of the bearing D. This flange D2 is provided with slots D3 for the passage of the segmental projections J. (See Figs. 3 and 6.)

On the outside, near the inner end of the ange D2, are formed the segmental projections D4, (see Fig. 3,) which fit into a corresponding groove formed on the inside of the collar K, (see Fig. 4,)-fitting over the offset I on the axle A, and provided with slots K for the passage of the said segmentalprojections D4. The collar K abuts against the inner face of the collar J, and is secured thereto by set-screws or other means.

In the odset l and the collar C of the axle A is formed a longitudinal aperture L, which opens at' its outer end into the groove L', formed on the spindle B and extending the entire length thereof. The inner end of the aperture L connects with the lubricating-reservoir N, held on the axle-beam O, secured in 'the usual manner Vto the axle A. The upper end of the reservoir N is closed by a springplate l?, pivoted on the axle-beam O. A guard Q, secured to the axle A, covers the top and sides ofthe outer en'd of the beam O and the collar K.

It will be seen that the lubricant placed in the reservoir N, which is located beyond the inside of the carriage-Wheel hub, passes, by means of the aperture L and the groove L.,

to the spindle B, between the latter and the bearing D. 4The latter, with its carriagewheel, is securely held on the axle by the collar J held on the inside of the collar C, and also by the, collar K, secured to the said collar J.' The spring H at the end of the spindle B takes up all lateral motion.

The collar K prevents dust and other impurities from getting onto the" spindle B.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.' rl"he combination, with a carriage-axle provided with an annular offset I and a col- IOO lar C on the inner end of the axle B, of a bearing D, fitting on the said axle-spindle and provided with an annular flange at its inner end having grooves and slots on the inside and segmental offsets on the outside, and a 'collar fitting on the annular offset of the axle and having segmental projections engaging the said groove of the Iiange, and a collar also fitting on the annular offset I of the axle and having grooves into which fit the external segmental projections on the flange of the bearing D, substantially as shown and described.

2. The combination, with the axle A, the spindle B, formed thereon and grooved on its upper side, the collar C on the inner end of the spindle and the oiiset I in rear of the collar, an aperture L, extending through the offset and collar, the bolster or beam O on top of the axle and having a vertical reservoir N leading into the aperture L, and the cover P therefor, of the bearing D, fitting on the spindle and having a securing-collar at its inner end in rear of the collar C, and the guard Q, secured to the axle and covering the oil.reservoir and joint between the said securing-collar, substantially as set forth.

3. The combination, with the spindle B, having an annular groove near its outer end and a collar C near its innel` enl,of the bearingD, having inner and outer securing-collars J K at its rear end, the said collars and bearing having interlocking recesses and projections, and the projections D on the outer end of the bearing of the cap or collar G, having recesses G for the passage of the projections D and the securing-screws.

4. The combinatiomwith the spind1e,of the bearing D, having a cap G on its outer end, and the spring H between the end of the spindle and the cap, substantially as set forth.

5. The combination, with the spindle B,l1av ing.,r the collar C at its inner end and the annular groove E near its outer end,of the bearing D, having securing-collars at its rear end, screws F, passing through it into the groove E, and the collar or cap G on the outer end of the bearing, substantially as set forth.
